葡萄膜黑色素瘤多药耐药基因的表达与患者预后因素的分析

目的 探讨葡萄膜黑色素瘤多药耐药基因的表达与患者预后的相关关系。 方法选择石蜡包埋葡萄膜黑色素瘤组织96例，通过脱色素免疫组织化学检测细胞周期素D1(cyclin D1)、上皮生长因子受体(epithelial growth factor receptor, EGFR)、转移抑制基因23(non-metastasis gene 23, nm 23)、P糖蛋白(P glucose protein,P-gp)、多药耐药相关蛋白(multidrug resistance relation protein,MRP)、肺耐药蛋白(lung-resistance-protein,LRP)基因表达。选择病例资料较完整者，进行随访，随访结果分类统计。 结果 96例葡萄膜黑色素瘤中类上皮细胞型21例、混合细胞型56 例和梭形细胞型19例，其中眼内期76例，眼外期20例。随着转移抑制基因nm 23表达的减低和Cyclin D1、EGFR表达的增高，耐药相关基因表达有增高趋势，其中MRP和LRP的表达与nm 23的表达呈明显负相关关系，与Cyclin D1、EGFR的表达呈明显正相关关系。随访结果显示，回访人数58例，生存超过 5年者26例，5年内死亡者19例。 结论 葡萄膜黑色素瘤多药耐药基因尤其LRP的表达与患者预后具有明显的相关性。 （中华眼底病杂志，2003，19：1-4）

Relationship of the gene of multidrug and drug resistance and the patients'' prognosis in uveal melanoma

Objective To probe the relationship between the patients′prognosis and the gene of multidrugs and drug resistance in uveal melanoma.Methods The gene expression of cyclin D1, epithelial growth factor receptor (EGFR), non-metastasis gene 23 (nm 23), P glucose protein (P-gp ) , multidrug resistance relation protein (MRP) and lung resistance protein (LRP) expression in 96 cases of uveal melanoma were detected by depigment immunohistochemistry. The patients with complete anamnesis data were observed continuously, and the follow-up results were classified. Results Among the 96 cases of uveal melanoma, the epithelioid cell type was in 21, the mixed cell type in 56, and the spindle cell type in 19 ; including 76 at intraocular stage and 20 at extraocular stage. As the level of metastasis suppress gene nm 23 expression decreased and the level of cyclin D1 and EGFR expression increased, the expression level of drug resistance genes increased. The levels of LRP and MRP had negative correlation to the expressions of nm 23 and postive correlation to the expressions of nm 23, Cyclin D1 and EGFR. In 58 patients′who were observed continuously, 19 died in 5 years and 26 survived over 5 years.Conclusion There are significant as sociation between patients′prognosis and multidrug and drug resistance gene in uveal melanoma.(Chin J Ocul Fundus Dis，2003，19：1-4)
